HINGE.

SPECIFICATION forming part of Letters Patent No. 416,044, dated November 26, 1889.

Application filed August 18, 1889 $erial No. 320,611. (No model.)

To alZ whom it may concern:

Be it known that I, JAMES UNVISE, a citizen of the United States of America, residing at Dow City,in the county of Crawford and State of Iowa, have invented certain new and useful Improvements in Door-Hinges; andIdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a-ppertains tomake and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to hinges for doors; and it consists in the improved construction hereinafter described and set forth, whereby a simple and efficient arrangement is provided.

In the accompanying drawings, forming part of this specification, Figure 1 is a View showing a portion of a door and its jamb and representing the employment of a hinge embodying my improvements. Fig. 2 is alike view showing-the hinges and central connectjug-sleeve in section.

The door A is connected to the jamb B by hinges consisting of the upper and lowerleaf members a b. Each of said members con sists of two sections, the butts c of each section secured to the door embracing the butts of the adjacent section secured to the jamb.

The opening in the upper butt 0 of the upper section and in the lower butt 0 of the lower section are both made square, and are adapted to receive the squared upper end of an upper rod 0 and corresponding lower end of alower rod-section D, said rods passing through the butts of both leaves of the upper and lower hinge-sections and serving as the pintle. Centrally on the door is secured a hinge section-or leaf E, through the butts (l of which the adjacent ends of the rod-sections pass' F is provided with a series of notches, each adapted to engage the edge of a dog G, pivotally secured on the body of the leaf.

In use the dog G is caused to engage the sleeve, so as to hold the same rigidly against axial revolution, and it will then be found that when the door is opened the upper and lower butts of the top and bottom members of the hinge attached to the door will, by reason of their square-ended connection, torsionally twist said springs against their rigid connection afforded by the sleeve and the dog, so that when the dooris released the flexion of the rods will restore it to its closed position.

An important feature connected with my improvement consists in the fact that the rods serve as the pintles for the disengaged butts of the leaves attached to the jamb, and thereby serve the dual purpose of terminal springs and pintles.

From the foregoing it will be apparent that the device embodying my improvements is of simple and inexpensive character and useful in operation. By employing the two distinct rod-sections the adjacent extremities of the same may be more conveniently squared for the engagement of the central sleeve than would be the case were asingle rod employed. Moreover, the two adjacent and independent ends enable distinct recesses to be made in the ends of the sleeve, so that the engagement of the rods with the same is not only seen red but thesleeve is relativelysuspended in position.

I claim- The combination, with the members of a door-hinge, the upper and lower butts of the upper and lower sections having squared recesses, as described, of rod-sections squareended to engage said recesses and serving as pintles, and j a sleeve having independent square recesses to receive the adjacent square ends of the rods, and a dog for engaging said sleeve to hold it and the adjacent rod ends fixed, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES U. WISE.
